Ghosting to the wrong disk

The other day I was starting up Norton Ghost to recover an old ghost image and setup a clean machine. I went through the menus as I usually do on autopilot, source, destination, etc…

Surprisingly, right before it started “doing it’s thing” I got the error message: “the destination disk could not be locked (643)”, I was baffled at first as I never encountered this error. Going back and trying again I noticed what happened. As I picked the destination disk, I used the wrong disk and marked one of the active disks instead of the clean one. Obviously the destination could not be used.

Why am I writing this useless piece of information??? You know who, knows exactly ;-)

peace to you all :-)

  • Many developers for Vista noticed all the new issues with editing and/or deleting registry keys. The new security measures turned the whole registry model to a major pain for developers.

    A first step to some would be to check if the key is WRP Protected or not. To do that do the following:
    Right click on the key -> Click Permissions -> Full Control would be only for TrustedInstaller (users/groupname tab) then the key is WRP. This means only Trusted Installers get to make changes to the key.

    Trusted Installer is a service that hosts code for install, update, and un-install of OS components. The service is trusted by the system to check for all the prerequisites such as package authenticity, signing authority and dependencies before making system changes.

    Vista’s speech recognition no jewel

    This may be funny or this may be sad, but this is the state of speech recognition in Windows Vista.

    Speech recognition was never perfect, some products are better than others. While some fail miserably others can definitely do a good job with proper training. Microsoft’s integrated speech recognition in Vista is no jewel, it has a proper interface and correction options, soon you will understand why they are required.

    Be aware! Some adult language… but I was holding my stomach laughing at some parts.

  • Who can really run Vista?

    According to a recent study, 94 percent of business PCs in North America do not meet the minimum requirements for Vista. Beside the fact that Microsoft tend to underestimate the real requirements of it’s systems upon release in published statements, the picture is pretty gloomy.

    About half of the average business PCs in North America are unable to meet the minimum requirements for Microsoft’s Windows Vista operating system, while 94 percent do not meet the system requirements for Vista Premium.

    Within these figures, 41 percent and 78 percent, respectively, require RAM upgrades to meet the minimum and premium system requirements of Vista, says a new study by Softchoice Corp., which is expected to be released later this week.

    In comparison, when Windows XP was released, some 71 percent of the PCs met its system requirements, Softchoice services consultant Dean Williams said in an executive summary of the report.

  • Restoration: File Recovery Freeware

    When a file is deleted from your computer, its contents aren’t immediately destroyed. Its hard drive space is made available for use, but until that space is overwritten, your old data is usually intact. Restoration by Brian Kato recovers such files on either FAT or NTFS partitions.

    Restoration is a freeware program that restores deleted files no longer in the Recycle Bin. Restoration works on Windows 9x 2000, NT and XP — on the Fat and NTFS file systems. It’s only 406 KB in size (and the 193 KB on the Windows 2000/XP version).

    Generally, the sooner you try to restore a file, the more successful you’ll be, since the more time passed since it’s been deleted it’s more likely to have been overwritten, this is especially critical on systems with low available disk space. Even if a file seems to be restored, there is no guarantee that the content is correct, check the files after you run the program.

  • At first is seemed like yet another blooper hits a big company. Microsoft Canada supposedly accidentally released Windows Vista pricing on Microsoft’s Canadian website. When the mistake was “found” the listings were remove promptly.
    Here are the prices as presented on the Canadian site (in US$):

    Vista Ultimate
    Upgrade: $269.931
    Full Retail: $450.581

    Vista Home Premium
    Upgrade: $179.691
    Full Retail: $269.931

    Vista Home Basic
    Upgrade: $116.483
    Full Retail: $233.862

    Vista Business
    Upgrade: $224.832
    Full Retail: $342.215

    However, all products and prices are already on Amazon. Kind of putting a dent in the leakage strategy, don’t you think?

    Shutdown Event Tracker provides a way for System Administrators and IT professionals to track and log why a servers are being restarted or shut down. It gathers the reasons users/administrators give for restarts and shutdowns to help create a comprehensive picture of an organization’s system environment.

    The whole idea behind the shutdown event tracker is that a server isn’t meant to be restarted or shutdown regularly. Therefore, when it is, administrators should keep a log of why the machine was powered down. However this feature is not suitable to all server mainly those who are restarted remotely without using the windows interface.

    Shutdown Event Tracker is enabled by default and supported on all Windows Server 2003 family of operating systems.

    To disable Shutdown Event Tracker perform the following:

    1. Log in as administrator
    2. Run gpedit.msc (group policy manager) in command prompt
    3. Go to Computer Configuration –> Administrative Templates –> System
    4. Double-click Display shutdown event tracker
    5. Change to Disable.
    6. Will take effect after reboot. If you want the changes to take affect immediately with a restart, refresh the GPO by running the following command: gpupdate /force

  • Last Thursday Microsoft published the minimum hardware requirements for Windows Vista. I was getting the feeling Vista’s specs skyrocketed out of proportion. Previous system requirements for Microsoft systems were usually above market level, and this was the base for the Wintel alliance, but this time it seems a little too much. I went around digging for the system requirements for all (not so recent) Microsoft systems. I was not surprised that this info was not to be found anywhere in the vast MSDN and TechNet networks.
